Investigators deemed Manso’s driving “careless” during the March 5 accident on the Tea Table Bridge in Islamorada, but found no sign of alcohol or drugs in blood tests. He was driving at a 60-mph rate — five miles per hour higher than the bridge’s speed limit.

The four victims, all friends from Spain who happened to be female lawyers vacationing in southern Florida, were driving a rented car when Manso’s truck, which was carrying portable toilets, smashed into the women’s car, which was sent skidding into the path of a large motor home.

The tremendous impact sent the ladies’ vehicle careening into a tree. The bloody accident scene was so gruesome that emergency personnel initially assumed there were only three victims.

While the dead women’s kin are suing Manso and the Florida company he is employed by for negligence, attorneys for Manso and his boss are pinning the blame on dead driver Margarita Cortes-Pardo, who, according to court documents, “negligently operated or maintained the motor vehicle in which she was riding so that it collided with Defendant’s motor vehicle.”

It will likely take about two years until a court date is set for the civil case.
